"I think you have different soul mates throughout your life, that your soul needs different things at different times," she says. "I do believe in love. I will always believe in love, but my idea has changed from what I've always thought."

Another change: Kardashian says she will start taking a more private approach with her next boyfriend – one that doesn't involve Keeping Up with the Kardashians or any of its spin-offs.

"I don't think I would stop [doing the reality show] – I love doing it – but I wouldn't have another relationship shown on the show," she says. "That might be too personal, especially when you're just meeting someone."

For now, Kardashian says she's "just going to work on me for a bit. ... I'm putting the past behind me and have never felt more confident about my future."
